What style blow-off valve should I run?

[sleepbattery]

I am looking to add a bov to my Fiesta but the options presented to me are confusing. Just got the car this year and had a Miata before it so, turbo engines are a new concept to me. I would like to have more performance output rather than just focus on minimal performance and more sound. My options are either the cp-e kit or one of the symposer delete kits. There is also the turbosmart kompact one. That one seems simple enough to install. Which ones do you think provide the best performance outputs?

Couple thoughts. First, what is your build plan overall?

On the stock turbo, it won’t matter which you pick. They’ll all hold boost better than the stock BPV. I’m a 90s kid and partial to the HKS sound because that’s what I grew up hearing when I first got into cars.

Do not get the exhale kit if you ever intend to put in an aftermarket radiator because larger diameter cold side pipes do not fit with bigger radiators. The stock cold side also flows pretty well. Most of us with big turbos and more than 300whp still run it. That said, your should definitely be looking at a radiator upgrade sooner rather than later being in Florida.

I’d get that turbosmart shortie plumb back since it includes the CEL defender if you plan to stay stock turbo, hybrid, or s280 since it’ll work with all of them.

If you’re going big turbo in the future, the turbosmart XS and HKS symposer kits are great. Pick the sound you prefer as they’re both excellent parts. I’ve been running a Mountune-spec turbosmart in the symposer location for more than 4 years without any hint of any issues whatsoever.

Whatever you do, make sure you get a CEL defender. It makes life much easier than tuning out the code. Or get the turbosmart electronic BOV.,

Any symposer replacement kit is a better choice over one that mounts directly to the turbo
Turbo mounted BOV's require maintenance and life expectancy drops considerably due to the heat from the turbocharger

My opinion TurboXS > HKS > Turbosmart Vee Port symposer kits

If you must go with a turbo mounted unit - the Turbosmart Kompact plumb back vacuum operated is what we have found to be the best for quickest reacting, least amount of maintenance, and require no adjustments after installation
